MAGNIFYlNG-GLOBE FOR THE DIFFUSION F ARTIFICIAL LIGHT.

SPECIFICATION forming part of Letters Patent No. 483,482, dated September 27, 1892.

Application filed November 2, 1891. Serial No. 410,556. (No model.)

.To all whom it may concern.-

Be it known that I, HILLIARY ELDRIDGE, of the city of Purvis, county of Marion, and State of Mississippi, have invented certain new and useful Improvements in Magnifying- Globes for the Diffusion of Artificial Light, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming a part hereof.

My invention relates to improvements in magnifying-globes for the diffusion of artificial light; and it consists in the novel arrangement and combination of parts, as will be more fully hereinafter described, and designated in the claims.

In the drawings, Figure 1 is a vertical longitudinal section of my complete invention, showing an incandescent lamp suspended therein. Fig. 2 is a horizontal cross-section taken on the line w w of Fig. 1, and Fig. 3 is a detail sectional view of a cap for securing the parts together which I employ in carrying out my invention.

The object of my invention is to construct a magnifying device for the diffusion and defraction of artificial light, and especially designed for a show-globe in stores.

I will give a further description of the use and object of my invention in connection with a mechanical description thereof.

Referring to the drawings, 1 indicates an outer spherical globe constructed of glass or any other suitable transparent substance, the same being provided with a neck 2. Said neck 2 is provided with a peripheral flange 3 and external screwthreads 4.

5 indicates a cap, for the purpose more fully hereinafter described, the same being pro vided with a flange 6, which flange 6 is provided with internal screw-threads 7. Said cap 5 is adapted to be screwed upon the externally-screw-threaded neck 2 of the globe 1. Said cap 5 is provided with a hole 8 for the insertion and removal of the source of light which is suspended within the magnifying device.

9 indicates an internally located globe. Said globe 9 is double concave in a longitudinal section when viewed sectionally, and is circular in a cross or transverse section, and is provided with a solid plano-ooncave end 10- that is, the end 10 is plano-concave when viewed externally or seen from a rear elevation when said globe is in its normal position. The globe 9 is provided with a neck 11, which is adapted to tightly fit in the neck 2, so as to effect a water-tight joint. The upper por* tion of the neck 11 is provided with an ex ternal peripheral flange 12, which is adapted to fit on the upper edge of the neck 2, which answers as a seat for said flange.

I will now proceed to give a description of the manner of constructing my invention. The aforesaid parts are made substantially of the form, as described. The internal globe 9 is suspended in the globe 1 with the flange 12 thereof resting on the edge of the neck 2, and then the cap 5 should be screwed onto the external screw-threaded neck 2, thus holding the globe 9 firmly and securely in its normal position, as can be readily perceived by inspecting the drawings. It may be noted in this connection that the globe 9 is provided with an open upper endfor the insertion and removal of the light. Of course in the practical operation and construction of myinvention I first fill the globe 1 with any desired liquid substance before the globe 9 is suspended within the same. It can be readily perceived, byany one versed at all in the principles of optics, that the light passing through the sides of the globe 9 will illuminate the contents of the globe 1 and produce an object of beauty to the observer.

In the drawings I have shown an ordinary incandescent lamp suspended within the globe 9; but I desire to state in this connection that I may use any other source of light.

Having fully described my invention, what I claim is- 1. A show-globe having an outer spherical globe 1 and an inner receptacle or globe 9, being double concave in longitudinal section, circular in cross-section, and provided with an open upper end and a plano-concave lower closed end, substantially as set forth.

2. A show-globe having an outer spherical globe 1, provided with a neck 2, an external peripheral flange 3, formed thereon or secured per end, and a flange 12, formed on or secured thereto, external screw-threads 4:, formed on to said upper end, substantially as set forth. 10
